Relaying mail through debian.org - anarcat
Back in 2020, I wrote this article about using DKIM to sign outgoing debian.org mail. This worked well for me for a while: outgoing mail was signed with DKIM and somehow was delivered. Maybe. Who knows.
But now we have a relay server which makes this kind of moot. So I have changed my configuration to use that relay instead of sending email on my own. It seems more reliable that mail seems to be coming from a real debian.org machine, so I'm hoping this will have better reputation than my current setup.
